How about some gas mileage reports?

[Quark]

I know they say if you're buying a big SUV you shouldn't care about the gas mileage but I'm not one of those. I would be quite interested to know what our courageous buyers are seeing especially on the 5.3L. Trips, combined city highway, from the DIC or hand calculated all will be appreciated. How fast you drive, load of vehicle, etc. the more info the better.

You show me yours, I’ll show you mine.

Haha, mine is a 2012 and averages from 19 to 22 depending on load and speed. If driving into the wind with a load of 500 lbs and driving 75mph it's closer to 19. With a tailwind at 70mph it's between 21 and 22mpg on trips. Short runs to town about 17 to 18mpg.

But my query is how do the 21s do on trips mostly. That's where the expense for me would be.

This is what I want to see...and I believe it....still looking for one....

I’d be highly skeptical of any V8 owner saying they regularly got in the 20’s. I had one in the mid 2015’s and reality was 14-16 city and 20 if I was drafting at 65 mph. Plus it took premium. That’s why I switched to all diesel vehicles......

21 Diesel mixed highway city 25mpg right now. I’ve seen 27.5 on 3 hour highway ride.

'32 Denali XL 6.2

12.5 mpg with 87
14 mpg with 93

21 Tahoe Z71.

20-23mpg highway

16 around town, but as low as 13mpg in winter around town.

Seems like the 21 gets worse than the 16 LT got. Still a great truck anway—maybe not broken in yet!

That's pretty good! I've only seen 19+ MPG once at 71 MPH!

2012 GMC Yukon SLE 2WD 5.3L and I get 18.5 MPG. I have a lead foot and drive the highway most of the time. I go to work early to beat the traffic and to get a parking spot close to the shop. On the way home it's like a slow moving parking so it's mostly stop & go or idling forward slowly. The price we pay for paradise!
